Planejamento do transporte urbano sustentável: uso de bicicletas no município de São Paulo-SP

From its foundation until nowadays, the city of São Paulo has undergone major transformation processes, one of the responsibles for these changes is the presence of efficient transportation ; From construction of roads and routes for the animal traction transportation, railroads, expansion and improvements to the introduction of the automobiles, highways, subway system, among others, all these changes are related to greater flow of people and goods. However nowadays has been reflected issues such as quality of life and development of society in a sustainable way, once we have the construction and reconstruction of space in benefit of capital, and therefore the valuation of individual motorized transport. The overuse of individual motor vehicles are generating an urban chaos, making it increasingly difficult to transit in big cities, the use of bicycles is presented as a viable modal alternative, allowing the flow, and enhancing the health of society and quality of the air

Voltammetric behaviour of a modified electrode with azide copper octa(3-aminopropyl)octasilsesquioxane composite in the oxidation of ascorbic acid

A novel nanostructured composite, azide copper octa (3-aminopropyl)octasilsesquioxane (ASCA) was incorporated into a graphite paste electrode and the electrochemical studies were conducted with cyclic voltammetry. The cyclic voltammogram of the modified graphite paste electrode with ASCA (GPE-ASCA), showed one redox couple with formal potential (E  ) = 0.30 V and an irreversible process at 1.1 V (vs Ag/AgCl; NaCl 1.0 mol L-1 ; v = 20 mV s-1 ). The redox couple with (E  ) = 0.30V presents an electrocatalytic response for determination of ascorbic acid. The modified electrode gives a linear range from 1.010-4 – 1.010-3 mol L-1 (r = 0.998) for the determination of ascorbic acid with detection limit of 6.910-5 mol L-1 and standard deviation of 2.3% for n = 3 . The amperometric sensitivity was 122.1 mA/mol L-1 for ascorbic acid. The application this electrode was tested and ascorbic acid in three commercial pharmaceutical product (Cebion, Cewin and Redoxon) have been determined.
